To all whom 'it may con-cern:

Be it known that: l, S'iewnnfr (j. Conr, a citizen ot' the UnitedStates, residing:r at Youngstown, in the county' oi h'lahoning and Stateof Ohio, haviinventi-il new and useful Improvements; in '.vlagneticflcclp Charging lachines. of which the ii'ollo'\.\'ing is ael'ieciiication.

My inventiox'i relates to machines for charging skclp into heatingiilrnaces preparatory to 'welding the :skein into tubes, or to bendingthe saine imo other products.

The objects of this invent-ion are to pro vide a rapid, simple andpositive means for charging skelp or other blanks oi a niagnetic orinagnetizabie nature into heating furnaces by the use of a magnetcarried by a suitable framework or charging table having travel acrossthe charging end of the furnace.

Referring to the accompanying drawings, Figure l is a longitudinal.`"faction through the shaft on which the coi' 'ing magnet mounted, partsbeing s ihoxn in elevation; Fig. 2, an end f iloifationo'f n striictllreon bodying i'ny invention Fig. a nien of the saine; and Fig. at, anelevation showing the 1 end opposite that shown on Fi 2, a portion ofthe furnace being shown in section.

lOn the dra-Winge., l represents a pair of' rails on which the wheels 2ot the charging table 3 travel.

et is a portion of a heating furnace across one end of which the t-abiemay 'travel back and forth. The ton of the tabie has two levels, theupper ci x v" preparatory to being; it n. f lower level. The sire-lp onthe 'opper le lie paraliel to the direction in which they are to becharged into the furnace. They are xifioved laterally by Workmen or byany suitable means so as to 'cause them to reach their proper positionon the lower level now to be described. The said lower level which maybe at any desired distance below the upper level is shown parallel tothe same. It has the conveying trou rh or channel 7 open upwardly, therebeing 1n the bottoni of the channel a number oftransverse rollers 8 onwhich the skelp travel with but little friction during the charginoperation in order to li h ten the work of t e charging magnet. At e end.of the charging channel or bed 7 I glace one or more rotary charging manets 9 aving its axis. of rotation transverse 'y of the direction inwhich the skelp is to 'be charged. The magnet preferably projectsslightly above the bottom of the channel 7. The magnet is driven by themotor 10 connected flieg-:cio by suitable gearing soA as to cause iin;tcp of thc magnet to rotate toward (he .fur

l1 .is .,.uitablc shaft, prf-.feralily of iron or steel, upon which lmount the core or 'spool lil., having thereon the coil 13 of Wire. Theterminals 1 4 andi?) of the coil lead 11especti'vc'ly 'to the collectorrings 16 and 17, carried by the core 1S on the shaft 11. The coil 13 andits spool 12 are inclosed in the cylindrical iron or steel cases 19which are magnetically'separated by the ring 2O of brass or othernon-magnetic material, this ring being at about the center line of theskclp. The outer ends of the cases 1 9 are and connected to the shaft11, the when the magnet is idle, be-

magnetic flux, nig along the bodies of .the cases 1-9, and across thenonmagnetic gap occupied by the ring 20.

"v'Vhen a slrelp is taken from the charging level 5 und placed in thetrough 7 with one end resting on the bodies of the cases .1,9 andbridging the gap occupied by the brass ring 20, thc .magnetic fiux justdescribed is largely di rerted so as to travel transversely through theskein at' and about its line of contact 'with the periphery oft themagnet. The ro- (ary magnet therciore, a great trac; tine or @i-resinefect on the slrelp and museali t te charged into the furnace at the.surface. velocity ci the magnet. The electric matar i() can, as weitknown, be controlled Se ae to gire the slreip such ini tial, final, @miiiitei'n'mdiate oi'nirging speeds as may pioveirst. After a skelp hasbeen charged into the furnace, the charging table 3 is moved on therails l to the desired posit-ion for charging another skelp into thefurnace.

My invention dispenses with a la-r e number of nien required for thehand ciarging 'of akelig; ci-iinmatesthe danger incidental and save-s bythat more than one magnet ay be used at selected places along theltrough, or near tho-Ina'gnet shown.- l I claim- 1.. The combination 'ofa furnace, a chargshaft 11, radiately along theing table at one endthereof, and a magnet thereon having surface travel toward the furnace,the said surface being arranged to be. engaged by linear magneticmaterials, and to transfer the same to the furnace.

2. The combination of a furnace, a charging table et the end thereof, arotary ma net having its axis of rotation transverse 0:' the table andfurnace, the `magnet bein arranged so that the part thereof whic r0-tates toward the furnace may be engaged by linear magnetizable material.

3. The combination of a table and a rotary magnet supported thereon andhaving its magnetic circuit interrupted eircumfern lthe table and havingits axis o Signed at Youngstown, Ohio7 this 15H' day of' December, 1911.
